Title:
WARNING METHOD OF AIR PRESSURE DROP OF TIRE AND DEVICE THEREOF
Document Type and Number:
Japanese Patent JP3594833
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the warning method of the air pressure drop of a tire which can improve the accuracy of the air pressure judgement of the tire.
SOLUTION: In the warning method of the air pressure drop for generating a warning, at the drop time of the inner pressure of the tire, after judging whether the air pressure of the tire is dropped or not based on the detected number of rotation after detecting the number of rotation of the tire, in the formula for calculating the judging value for detecting the reduced pressure of the tire, by comparing the difference of two diagonal sum, a correction term on the difference of the tread width between the front/rear wheels of a vehicle is provided.
